President Donald Trump solicited interference from Ukraine to influence the 2020 US elections, and the White House intervened to “lock down” the transcript of the call, a whistleblower said in a complaint released on Thursday.

“I have received information from multiple US government officials that the president of the United States is using the power of his office to solicit interference from a foreign country in the 2020 US election,” the whistleblower, an unidentified intelligence community official, wrote in the complaint released by Congress.

The whistleblower said White House officials had expressed alarm about the gravity of Trump’s call with his Ukrainian counterpart, and that they told the whistleblower that they had likely “witnessed the president abuse his office for personal gain.”

The document was released ahead of scheduled testimony from Joseph Maguire, the acting director of national intelligence. House Democrats who are now mulling Trump’s impeachment are hoping Maguire will explain why he withheld the intelligence community whistleblower’s complaint from Congress for weeks.

Lawmakers have been given a redacted, declassified version of the complaint that can be made public.

The complaint is at least in part related to the July phone call between Trump and Ukrainian President Volodymyr Zelenskiy in which Trump prodded Zelenskiy to investigate former Vice President and potential election rival Joe Biden.

The White House released a rough transcript of that call on Wednesday morning. House Speaker Nancy Pelosi on Tuesday endorsed an impeachment investigation in light of the Ukraine revelations. (AP, AFP)
